Pull the fuel pump relay, on the bottom it tells you the contact numbers. 30 is power in from the fusible link, 87 is power out to the pump (with the relay activated), 86 is power from the ignition switch, 85 is the ground through the ECU to activate the relay.
If you have power to 30 and power to 87 with the key on. The problem is downstream from the relay or the activation ground circuit through the ECU.
With an ohm meter you can do a quick circuit test from the 87 pin at the fuel pump relay socket to ground, there should be continity, with some resistance for the pump windings. If you have an open circuit, it's likely a broken wire or a corroded connector.
You can feel if the relay clicks, when the key is turned on.
If there is a break in the wire from the relay 87 pin downstream someplace, you may want to start by dismounting the relay block and turning it over (carefully) and looking at the bottom. It gets pretty darned nasty under there. If I remember correctly the cable goes through the bulkhead connector and under the drivers and passenger door sill plastic panels. And through three or four connectors. The wire changes colors at least once somehwere in the middle of the run and then back again to I think orange or orange with a black stripe.
Something else to keep in mind, the fuel pump needs a lot of juice. A poor connection may test good for voltage, but not pass enough amperage to run the pump, which makes troubleshooting really fun.
Something else that can throw you, some of the fuel pump relays are wired backwords. The 30 and the 87 may be wired backwords. The 85 and 86 may be wired backwords.
The fuel pump relay may even be in the a position different from the book says.
